1.2. Specifications
* When powered from USB (BUS power), current is measured on the 5V USB bus. When externally powered (Self power), current is
measured with a 9V supply. External power follows a constant-power curve and external voltage can vary 7 - 28V.
** If the supply voltage for a given power setting is lower than the minimum supply voltage requirement (as shown in Table 1-02), the
TX Power Output will decrease to the highest power level setting given the current supply voltage.
*** 500mW and 1W power outputs are not supported when using BUS power.
